MU SlC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 451,763, dated May 5,1891.

Application filed January 6, 1891.

To all whom it may concern.-

Be it known that I, FRANK M. HURLEY, of Bennington, in the county ofMorrow and State of Ohio, have invented certain new and usefulImprovements in Music-Leaf Turners; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in music-leaf turners; and itconsists in, first, the combination of a suitable number of bent rodswhich carry adjustable clamps at their upper ends and toothed wheels attheir lower ones, and a corresponding number of toothed push-rods, bymeans of which the bent rods are made to turn the leaves, and,second,the combination of two verticallyadjustable rods, an adjustableframe placed thereon, and a springactuated, endwise-moving, andpartially-rotating rod provided with devices for catching over the upperends of the leaves, as will be more fully described hereinafter.

The object of my invention is to produce a music-leaf turner by means ofwhich the music can be quickly and readily turned without the performerhaving to stop an appreciablelength of time in playing to turn them.

Figurel is a front elevation of a leaf-turner which embodies myinvention. Fig. 2 is a plan view of the same, the upper portion of therods for turning the leaves being removed. Fig. 3 is an end view.

A represents the base-piece, from the top of which rises the board B,which is cut away at the center of its top edge, as shown, so as toreceive the frame 0, which is placed upon the two vertically-adjustablerods D, which are inserted in holes made in the top edge of the board B.These rods can be raised and lowered at will, so as to enable the frame0 to be adjusted according to the height of the music or book beingused. J ournaled in this frame O is an endwise-moving partially-turningrod H, to which the spring I is applied for causing the rod to partiallyrevolve whenever it is left free to move. Projecting from the rod arethe two arms J, which catch over the upper-edges of the two outer leavesor ,sheets of music.

the covers and those leaves which are not to be brought into use. Inorder to hold these arms in a raised position when not in use, one endof the rod has a shoulder K formed upon it, and this shoulder catchesunder a corresponding shoulder or flange L upon one end of the frame 0.As soon as the rod is moved endwise by means of its handle N against thepressure of the spring the shoulder upon the end of the rod is movedfrom under the shoulder upon the frame, and then the spring exerts itstension in turning the rod so as to turn the arms down over the top ofthe outer pages or back of the music.

In order to hold the frame 0 at any desired position upon the twovertical rods, a spring 0 is secured to the top of the frame, and theends of this spring bear against the rods, so as to exert a frictionalcontact thereon.

Secured to opposite ends of the base A are the two spring-wires P, whichcatch against the lower edges of the outer sheets, the back, or theleaves that are not to be brought into use. Rising from the top of thisbase A are the two pins Q, behind which these wires are made to catchwhen they are not to be brought into use.

Extending from the front of and through a portion of the base A are anumber of pushrods R, which are provided with suitable buttons orhandles at their outer ends, and which have cogs or teeth formed uponone side of their inner ends for the purpose of operating the smalltoothed wheels S, placed upon the lower ends of the rods T, for turningthe Only one of the push-rods is made straight, while each one of theothers is bent so as to bring all of their inner ends in avertical linewith each other. The wheels and the bent portions of the push-rods areplaced in a recess formed in the top of the rear edge of the base A, andthe wheels are placed one above the other, so that one rod will notinterfere with the other as it is brought into use. The operating-rodsextend upward from their wheels through a suitable bearingU, and havetheir upper ends bent at right angles, so as to receive, the adjustablerods V, which are passed through them, and which rods have their clampsWV secured to their lower ends for catching hold of the upper edges ofthe sheets of music. hen the push-rods are successively pulled out, theyturn the sheets of music connected to them and more quickly and readilythan could be done it the operator were to use his or her hands.

Having thus described my invention, I claim 1. The combination of thevertical boa-rd, the vertically-adjustable rods placed therein, theadjustable frame placed upon the rods,thespring-actuatedendwise-moving'partiallyturning rod provided witharms, and a shoulder at one end to engage With a corresponding' shoulderupon the frame, substantially as shown.

2. The combination of the base, the board B, which rises therefrom, thevertically-adj ustable rods placed in recesses in the board, thevertically-adjustable frame placed upon the rods, a spring secured tothe frame and bearing against the rods, and a spring-actuated,endwise-moving, and partially-revolving rod provided with arms,substantially as described.

3. The combination of the push-rods having their inner ends providedwith teeth, with the
